BACKGROUND: There is a need for more powerful methods to identify low-effect SNPs that contribute to hereditary COPD pathogenesis. We hypothesized that SNPs contributing to COPD risk through cis-regulatory effects are enriched in genes comprised by bronchial epithelial cell (BEC) expression patterns associated with COPD. METHODS: To test this hypothesis, normal BEC specimens were obtained by bronchoscopy from 60 subjects: 30 subjects with COPD defined by spirometry (FEV1/FVC < 0...

The prevalence of chronic obstructive pulmonary disease (COPD) has increased more rapidly in women than in men during the past two decades. Clinical presentation, comorbidities and prognosis may differ between genders and may influence management decisions. The influence of gender on COPD expression has not been clearly explained to date. Thus, the aim of this study was to evaluate significant differences between women and men suffering from COPD, regarding clinical presentation, pulmonary function test results, comorbidities, and prognosis...

Background: Chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death in the world, for which smoking is a common cause. It is preferable to diagnose COPD at an earlier stage and to assess its progression so that mortality and morbidity of the disease could be reduced. Hence, we conducted this study to assess parameters of body plethysmography in Indian population where the data are lacking and to assess whether the use of body plethysmography can detect COPD earlier...

Spirometry is a widely used pulmonary function test to detect the airflow limitations associated with various obstructive lung diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and even obesity-related complications. These conditions arise due to the change in the airway resistance, alveolar compliance, and inductance values. Currently, zero-dimensional (0D) compartmental models are commonly used for calibrating these resistance, compliance, and inductance values, i.e., solving the inverse spirometry problem...

BACKGROUND: The transition from early childhood wheezing to persistent asthma is linked to lung function impairment over time. Little is known how the methods used to study lung function at different ages correlate longitudinally. METHODS: Sixty-four children with a history of hospitalization for bronchiolitis before 6 months of age were prospectively studied with impulse oscillometry (IOS) at the mean age of 6.3 years and these preschool IOS results were compared with flow-volume spirometry (FVS) measurements at mean age of 11...

AIM: Inflammation is a major factor in the pathophysiology of bronchopulmonary dysplasia (BPD) and it contributes to accelerated telomere shortening and cellular aging. This study aimed to determine its effect on telomere length and lung function in school-aged children born preterm with BPD. METHODS: We examined 29 children with BPD, born preterm in Stockholm county 1998-99, along with 28 children with allergic asthma born at term matched for age and gender. At 10 years of age, we measured relative telomere length (RTL) in blood by quantitative polymerase chain reaction, lung function by spirometry and inflammation by fractional exhaled nitric oxide and blood cytokines...

BACKGROUND: More than 90% of the world's population lives in areas where outdoor air pollution levels exceed health-based limits. In these areas, individuals may use indoor air filtration, often on a sporadic basis, in their residences to reduce exposure to respirable particles (PM2.5 ). Whether this intervention can lead to improvements in health outcomes has not been evaluated. METHODS: Seventy non-smoking healthy adults, aged 19 to 26 years, received both true and sham indoor air filtration in a double-blinded randomized crossover study...
